Winter in Guwahati and across Assam brings cool breezes, pleasant mornings, and a welcome break from humidity. However, the season also brings a significant rise in respiratory problems. For many people—especially children, the elderly, and individuals with asthma, COPD, allergies, or weak immunity—the winter months can be challenging. Cold air, sudden temperature changes, viral infections, indoor pollution, and low humidity can irritate the airways and trigger breathing difficulties.

 

Why Do Respiratory Problems Increase in Winter?

Many people believe that cold weather alone causes breathing issues, but the reasons are more complex. Winter creates multiple environmental and biological changes that affect the lungs.

1. Cold and Dry Air Irritates the Airways

The nose and lungs work best when the air is warm and moist. During winter, the air becomes colder and drier. Breathing this dry air can irritate the lining of the airways, causing inflammation. This leads to:

  • Persistent dry cough
  • Throat irritation
  • Wheezing
  • Tightness in the chest

People with asthma and chronic bronchitis experience more frequent attacks in winter because the cold air narrows the air passages.

2. Viral Infections Spread More Easily

Winter is known as the “cold and flu season” because viruses survive longer in cold temperatures. People also spend more time indoors, allowing infections to spread quickly. Common respiratory infections include:

  • The common cold
  • Influenza
  • Viral bronchitis
  • Respiratory syncytial virus (RSV) infection
  • COVID-19

These viral infections can worsen pre-existing lung diseases and may lead to pneumonia in vulnerable individuals.

3. Indoor Air Pollution Levels Rise

During winter, people spend long hours indoors with closed windows. This reduces ventilation and increases exposure to indoor pollutants such as:

  • Dust
  • Mold spores
  • Smoke from cooking
  • Scented candles or incense
  • Room heaters
  • Pet dander

These irritants can trigger allergies, asthma attacks, and respiratory discomfort.

4. Seasonal Smog and Pollution

In many Indian cities, including Guwahati, the winter months see a spike in pollution due to stagnant air, vehicle emissions, and waste burning. Pollution particles enter deep into the lungs, leading to coughing fits, irritation, breathlessness, and worsening of chronic respiratory diseases.

5. Reduced Immunity in Winter

The body’s immune system naturally becomes less active during the cold season. When immunity drops, the risk of infections increases. This is one reason why winter illnesses spread widely among children and the elderly.

 

Common Respiratory Problems in Winter

Winter affects people differently depending on their health, environment, and immune strength. These are the most common respiratory conditions seen during winter in Assam and across India.

1. Asthma Attacks

Asthma is one of the most common winter-related respiratory illnesses. Cold air constricts the airways and triggers inflammation. Pollution and viral infections make asthma symptoms even worse.

Common winter asthma symptoms include:

  • Frequent coughing
  • Wheezing sound while breathing
  • Shortness of breath
  • Chest tightness
  • Increased use of inhalers

Children with asthma are especially vulnerable in winter.

2. Allergic Rhinitis

People with seasonal allergies often experience worsened symptoms in winter due to indoor allergens like dust mites, mold, and pet hair.

Symptoms include:

  • Sneezing
  • Runny or blocked nose
  • Itchy throat
  • Watering eyes

Though allergic rhinitis is not dangerous, it can significantly affect daily life if not treated.

3. Common Cold and Flu

These viral infections occur more frequently in winter. While most cases resolve in a few days, they can sometimes lead to complications like sinusitis, bronchitis, or pneumonia, especially in those with weak immunity.

4. Acute and Chronic Bronchitis

Acute bronchitis is inflammation of the airways due to viral infections. It causes:

  • Persistent cough
  • Thick mucus
  • Fever
  • Body ache

Chronic bronchitis, a type of COPD, worsens significantly in winter due to cold air and pollutants. Patients may experience severe breathlessness and prolonged coughing episodes.

5. Pneumonia

Pneumonia can be viral, bacterial, or fungal. Winter increases the risk of pneumonia, especially in:

  • Children
  • Elderly people
  • Smokers
  • People with asthma or COPD
  • Patients with diabetes or heart disease

Early treatment is essential to prevent complications.

6. COPD Exacerbations

COPD (Chronic Obstructive Pulmonary Disease) includes chronic bronchitis and emphysema. Winter is the most dangerous season for COPD patients. Even mild exposure to cold air can cause:

  • Sudden breathlessness
  • Wheezing
  • Increased mucus production
  • Chest infection

COPD patients must take extra precautions during winter months.

7. Throat Irritation and Dry Cough

Dry and cold air strips moisture from the airways, leading to irritation, throat dryness, and persistent dry cough. People who use room heaters without humidifiers often face this problem.

8. Sinusitis

Cold weather can cause sinus inflammation, leading to blocked sinuses, headaches, facial pressure, and nasal discharge.

 

Who Is Most at Risk During Winter?

While winter respiratory issues can affect anyone, certain groups are more vulnerable:

  • Children below 10 years
  • Elderly above 60 years
  • People with asthma, COPD, bronchitis
  • Diabetic and heart patients
  • Smokers
  • Individuals with low immunity
  • People exposed to pollution or dust
  • Those with a history of allergies

These individuals must take extra precautions during winter.

 

Early Symptoms You Should Never Ignore

Winter respiratory illnesses often begin with mild symptoms. Recognising them early can prevent complications.

Look out for:

  • Persistent cough
  • Difficulty in breathing
  • Wheezing noises
  • Fever with chills
  • Chest pain or tightness
  • Thick yellow or green mucus
  • Tiredness or fatigue
  • Sore throat
  • Blocked or runny nose

If symptoms last longer than three days, worsen, or interfere with daily activities, consult a pulmonologist immediately.

 

How to Prevent Respiratory Problems in Winter

Prevention is always better than cure. With the right habits and lifestyle measures, most winter respiratory issues can be controlled.

1. Keep Your Home Well-Ventilated

Even in winter, stale indoor air can trap pollutants. Open windows for a few minutes daily to improve air circulation. Use exhaust fans while cooking.

2. Wear Masks When Outdoors

Masks protect against cold air, pollution, and allergens. People with asthma or COPD should always cover their nose and mouth when stepping outside.

3. Use a Humidifier

Humidifiers add moisture to dry indoor air, preventing throat irritation and dry cough. You can also keep a bowl of water near the heater.

4. Stay Warm

Sudden exposure to cold air can trigger breathing issues. Wear scarves, warm shawls, gloves, and socks, especially in the early morning and late evening.

5. Stay Hydrated

Drinking warm water keeps the airways moist and helps reduce mucus thickness.

6. Adopt Good Hygiene Practices

Wash hands regularly, avoid touching your face, and maintain good hygiene to prevent viral infections.

7. Avoid Smoking and Smoke Exposure

Smoking destroys lung health and increases vulnerability to winter infections. Even exposure to second-hand smoke is harmful.

8. Manage Indoor Dust

Clean carpets, curtains, and bedding regularly. Dust mites multiply in winter and trigger allergies.

9. Eat a Nutritious Diet

Include foods rich in vitamin C, zinc, and antioxidants to boost immunity. Warm soups and herbal drinks help soothe the throat.

10. Take Your Medications on Time

Patients with asthma or COPD must continue their prescribed inhalers and medicines even if they feel better. Never skip doses in winter.

11. Get Vaccinated

Seasonal flu vaccines and pneumococcal vaccines are beneficial for vulnerable groups. Consult your doctor for guidance.

12. Practice Breathing Exercises

Breathing exercises improve lung capacity and reduce stress on the respiratory system. Simple practices like deep breathing, pursed-lip breathing, and steam inhalation can help.

 

When Should You Consult a Pulmonologist?

Immediate medical attention is required if you experience:

  • Breathlessness even at rest
  • High fever that does not reduce
  • Chest pain
  • Cough lasting more than two weeks
  • Coughing up blood
  • Blue lips or fingertips
  • Severe wheezing
  • Reduced oxygen levels

Delaying treatment can worsen infections and cause complications. Lung diseases are best managed when diagnosed early.
